DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0025] The indirector light fixture 10 of the present invention is
depicted in FIG. 1. As shown therein, the reflector housing or
fixture head 30 is held outward from a ballast housing 20 by
support arms 40, 41. The ballast housing 20, as shown in FIG. 1,
may be affixed to a vertical surface, such as a wall, by a ballast
house mount plate 11 which will allow the ballast housing to mount
to the wall or, alternatively, to a ceiling.
[0026] As shown in FIG. 1, the indirector light fixture 10 of the
present invention has a mount plate 11, ballast housing 20,
reflector housing 30 and a lens cover 31. Within the ballast
housing are the ballast and other electronics necessary for
providing adequate electrical current to the lamp 33 contained
within the reflector housing 30. As is typically the case, the
ballast electronics contained within the ballast housing are
separated from the lamp within the reflector housing 30 such that
the heating characteristics of the two elements remain separate and
therefore do not cause overheating conditions. However, alternative
electrical connection and assemblies may be utilized while also
incorporating the various features of the present invention and the
specific electrical connections as well as electrical
configurations depicted herein should not be considered limiting.
As such, the present invention covers such alternative connections
and assembly constructs such as combination ballast electronics and
lamp electronics.
[0027] As further shown in FIG. 1, it is apparent that the support
arms 40, 41 may rotate about a hinge or pivot point on one or both
of the ballast housing 20 and the reflector housing 30. This allows
for accurate adjustment of the lens and reflector housing 31, 30
such that the ballast housing and mount plate, when mounted to
either a vertical or horizontal surface, may not negatively impact
the direction of the light output from the lamp and reflector
housing.
[0028] As shown in FIG. 2 and in FIG. 3, access to the interior of
the reflector housing 30 may be accomplished by loosening of the
lens attachment screws 32. After removal of the screws 32, the lens
may be raised thereby exposing the interior of the reflector
housing 30 as depicted in FIG. 3. As depicted in both FIG. 2 and
FIG. 3, removal of the lens attachments screws 32 allows the lens
to be raised and then slid outward from the rear portion of the
reflector housing. The reflector housing 30 may therefore be
exposed allowing access to the interior of the housing and exposing
the lamp socket 36a and lamp 33. Such access may be desirable for
servicing of the indirector light fixture 10, replacement of the
lamp 33 or adjustment of the reflector 34 contained within the
reflector housing 30.
[0029] Lamp 33 may be a high intensity discharge (HID) lamp in
order to increase the output luminosity of the indirector light
fixture 10 of the present invention. Of course, other lamps or
light emission device may be utilized within the reflector housing
30 of the present invention such as ARC lamps, compact fluorescent
or other light sources.
[0030] As shown in combination with FIG. 3 and FIG. 4, the
reflector 34 retained within the reflector housing 30 may be
adjustable. The reflector 34 may be hingedly affixed to a rear
portion of the reflector housing 30 by hinge members 60 such that
the reflector 34 may be adjusted within the reflector housing. As
shown in FIG. 3 and FIG. 4, the reflector housing may be adjusted
by the reflector adjustment screws 35 placed along the forward or
front portion of the side of the reflector 34. As can be seen in
conjunction with the exploded view of the light fixture in FIG. 6,
the adjustment screws 35 retain the reflector within the reflector
housing at a desired angle by biasing the reflector upward through
the use of reflector bias springs 35a which force the reflector
upward against the head of the reflector screws 35 in combination
with the hinges 60. As such, as depicted in FIG. 4 and FIG. 3, the
reflector may be adjusted internally of the reflector housing by
either tightening or loosening the reflector screw 35.
[0031] Further, as shown in FIG. 4, along the inner side wall of
the reflector housing side wall 36 are the reflector angle markings
37 which allows the user to adjust the internal reflector to a
predefined angle of deflection. As shown in the figures, the
reflector 34 may be field adjusted upwards or downwards for
customer desired light distribution. A deflection of up to
10.degree. may be provided utilizing the adjustment screws 35 but
increased deflection may be accomplished by increasing the
adjustment screw length 35 in combination with the biasing springs
35a.
[0032] As shown in the figures, the internal reflector 34 may be
adjusted about the hinges 60 thereby causing deflection of the
light without movement of the reflector housing 30 or support arms
40 and 41. Thus, the reflector adjustment screws 35 provide an
alternative means for adjustment of the internal reflector 34. As
can be seen in FIG. 6, the reflector adjustment screws 35 extend
through the apertures in the sides of the reflector 34 and extend
downward into threaded openings within the reflector housing 30.
Interposed therebetween are the biasing springs 35a thereby forcing
upward bias against washers and, concurrently, the underside of the
frame of the reflector 34 thereby causing the reflector 34 to
rotate about hinge members 60. Markings 37 can provide an
indication as to the degree to which the reflector is adjusted
relative to the flat horizontal plane defined by the top of the
reflector housing 30 and lens 31. Of course, if the reflector
housing 30 is not at a level position due to the adjustment of the
support arms 40 and 41, additional measurements may be necessary in
order to properly position the reflector 34 to the desired angular
displacement.
[0033] Turning to FIGS. 5-10, an alternative mechanism for
adjusting the reflector housing and the support arm angle is
provided within the support arms and ballast housing connection. As
shown in FIG. 5 wherein a single side of the indirector light
fixture 10 of the present invention is depicted, the support arm
may be positioned relative to the mounted ballast housing 20 such
that the reflector housing 30 is properly positioned to a desired
level. FIG. 5 depicts only a single support arm but both support
arms may incorporate the ratchet and pawl mechanism described
herein. As shown in the figures, the support arm 41 may be adjusted
to a desired angle relative to the ballast housing 20. The support
arm 41, which supports the reflector housing 30 relative to the
ballast housing 20 as the ballast housing 20 is mounted to a wall
or ceiling, maintains the reflector housing 30 in a supported
position preventing the downward travel of the reflector housing
about the hinge pin 42. The support arm 41 is maintained in the
supported position by a ratchet and pawl mechanism integrated into
the support arm 41 and the ballast side wall 22 and support plate
23. The ratchet and pawl mechanism will allow for the upward or
clockwise rotation of the reflector housing 30 about hinge pin 42
while preventing downward travel or counter clockwise travel about
hinge pin 42. The design of the ratchet and pawl integrated within
the support arm 41 will therefore allow for adjustment of the
support arm angle upward and lock the reflector housing in place
while allowing upward travel at 15.degree. increments. Various
incremental displacements from the ballast housing 20 may be
provided For example, if the ballast housing is mounted along a
vertical wall as depicted, the ratchet and pawl mechanism may allow
for support from 30.degree. downward from a horizontal plane to
60.degree. up from the same horizontal plane. As depicted in FIG.
5a-5c, various aspects of the ratchet and pawl construction within
the support arm 41 are provided. As will be described herein within
the ratchet and pawl assembly, the reflector housing can be raised
to its upright position as depicted in FIG. 5a to release the pawl
from the ratchet teeth thereby allowing for downward travel and
resetting of the fixture head and any desired position within the
increments supported as is shown in FIGS. 5b and 5c.
[0034] As shown in conjunction with FIGS. 6, 7, 8 and 9, the
support arm 41 has formed therein a first distal end ratchet teeth
47 as depicted in FIG. 7. The support arm 41, as seen in FIG. 6, is
comprised of inner plate 44 and outer plate 43 with sliding cover
26 positioned between the inner plate 44 and support mount plate
23. Support arm 41 has formed a plurality of ratchet teeth 47 which
work in combination with a pawl residing on the outer surface of
support mount plate 23. The pawl 24 works in conjunction with the
ratchet teeth to prevent downward or counter clockwise travel of
the support arm and reflector housing about pin 42. As can be seen
in conjunction with FIGS. 7, 8, 9 and 10, the ratchet and pawl
design integrated within the support arm 41 and support mount plate
23 allows the reflector housing to be positioned at a desired level
while supporting the reflector housing 30 in a desired
position.
[0035] As seen in FIG. 7, the ratchet teeth 47 are positioned along
an interior surface of the support arm 41. As previously indicated,
the inner plate 44 and outer plate 43 of the support arm 41 forms a
hollow area therebetween thereby creating the opening within which
the ratchet teeth 47 are formed. The ratchet teeth work in
conjunction with the open or reset position 48 within the teeth as
well as the closing ratchet 49 which are designed to position the
pawl 24 in a desired orientation relative to the ratchet 47.
[0036] As indicated, the desired functionality of the ratchet and
pawl mechanism integrated design set forth within the support arm
41 and support mount plate 23 is such that the pawl 24 prevents
downward or counter clockwise rotation about hinge pin 42. However
it is desirable that the reflector housing 30 may be rotated
clockwise about the hinge pin 42 and allows proper support of the
reflector housing 30 thereby preventing counter clockwise rotation.
Additionally it is desired that the ratchet and pawl mechanism
allow the pawl 24 to be reset so that when the reflector housing
and support arm are positioned at its upper most position as
depicted in FIG. 5a, the pawl 24 is placed in an inactive position
thereby preventing the pawl tooth 39, shown in FIG. 8, from
engaging the ratchet teeth 47 on support arm 41. Thus, when the
reflector housing 30 and support arm 41 are positioned as depicted
in FIG. 5a, the pawl is forced into the unengaged position shown in
FIG. 8 thereby preventing the pawl tooth 39 from engaging the
ratchet teeth 47. In such a position when the reflector housing is
positioned to reset the ratchet and pawl mechanism, the pawl tooth
39 is positioned within the open reset position 48 causing the pawl
tooth 39 to disengage the ratchet teeth 47. Pawl bias clip 25,
shown in the figures, retains the pawl in the desired position by
having first clip end 29 and second clip end 28 maintain the pawl
in the proper orientation. Thus, as depicted in FIG. 8, the pawl 24
is maintained in the unengaged position thereby preventing the pawl
tooth 39 from engaging the ratchet teeth 47.
[0037] As seen in FIG. 8, the support mount plate 23, which is
mounted on the end of the ballast housing 20 adjacent the ballast
housing side wall 22, allows the pawl 24 to rotate about a center
pivot point. Once the pawl 24 is in the position depicted in FIG.
8, the reflector housing 30 may be lowered to the lower most
position as shown in FIG. 5b which causes the pawl 24 to engage the
closing ratchet 49 thereby forcing the pawl to rotate and the pawl
tooth 39 outward to engage ratchet teeth 47. Continued clockwise
rotation of the reflector housing 30 about the hinge pin 42 allows
the reflector housing to be supported in predefined increments
depending on the position of the ratchet teeth 47 within the
support arm 41.
[0038] As shown in FIG. 8 and FIG. 10, the pawl bias clip 25 allows
for the pawl to be held or maintained in the unengaged position
thereby allowing the reflector housing 30 to be reset and rotated
counterclockwise about hinge pin 42. Biasing clip 25, as shown in
FIG. 6, may extend through the ballast housing side wall 22 and
support mount plate 23 such that the ends engage the pawl 24.
However, a number of biasing mechanisms are well known in the art
for properly biasing a pawl against a ratchet area or ratchet
wheel. Further, the exact configuration of the ratchet and pawl
mechanism depicted within the figures is not considered to be
narrowing in scope as modifications to the pawl and ratchet
assembly are considered to be covered that incorporated by the
teachings herein. Thus, various constructions of ratchet and pawl
mechanisms used in conjunction with the support arms and housing
members are felt to be incorporated within the teachings
hereof.
[0039] The ratchet and pawl mechanism configuration integrated
within the support arm 41 described herein may be provided on a
single support arm or on both support arms 40, 41 dependent upon
the functionality required for support of the reflector housing.
Thus, where heavier reflector housings 30 are present, it may be
necessary to provide a secondary support mechanism. The support arm
design which incorporates the ratchet and pawl mechanism allows for
an additional method for adjusting the angle of deflection of light
emitted from the reflector housing 30 in addition to altering the
deflection of the actual reflector previously mentioned.
[0040] Additionally, as shown in FIG. 3, pin 62 may also be
loosened thereby allowing rotation of the reflector housing 30
about pin 62 on support arm 41. An additional pin may be provided
on support arm 40 on the opposite side. Thus, as shown in FIGS. 11
and 11b, markings 63 on the support arm 41 may provide additional
adjustment of the reflector housing 30 in addition to the
adjustment of the reflector and adjustment of the support arms 41
in relationship to the ballast housing 20. Thus, the design of the
present invention allows for three different angular adjustments of
the light emitted from the reflector housing 30 depending upon the
end users needs and ultimate configuration.
[0041] As depicted in the figures, the ballast electronics are
connected to the lamp by ballast feed wire 45. As seen, the ballast
feed wires are positioned from the ballast housing 20 through the
support arm 41 such that they are not evident on the exterior of
the indirector light fixture 10 of the present invention. Thus,
inner plate 44 and outer plate 43 of support arm 41 provide a
hollow space through which the ballast feed wire 45 may be threaded
such that the feed wires 45 extend from the ballast housing 20,
through the interior of support arm 41 between inner plate 44 and
outer plate 43 and into the interior of the reflector housing 30
such that adequate current may be provided to lamp 30 through lamp
socket 36a. The ballast feed wires are more readily shown in FIG. 7
and 8 as the feed wires are threaded through the support mount
plate 23 into the interior of the support arm 41. As shown in FIG.
6, the feed wires are additionally fed back through the inner plate
44 to the interior of the reflector housing 30 such that the
ballast feed wires never are positioned on the exterior of any of
the structure of the fixture 10. Thus, the feed wires 45 are
contained entirely within the interior of the fixture thereby
providing easier connection and installation of the entire fixture
10. As indicated, such a design is possible by having the interior
of the support arm 41 formed between the inner plate 44 and outer
plate 43 such that the wires may be fed therethrough although
alternative constructs may be used to accomplish the same
effect.
[0042] The indirector light fixture 10 of the present invention as
described herein and shown in the drawings therefore has a
plurality of mechanisms through which the reflector housing 30 may
be adjusted. The reflector 34 may be adjusted within the internal
construct of the reflector housing 30 by adjusting the reflector
adjustment screws 35 thereby allowing the biasing springs 35a to
raise or lower the reflector 34 within the housing 30.
Alternatively, the entire reflector housing 30 and support arms 40,
41 may be raised or lowered and supported in position by a ratchet
and pawl mechanism. However, a number of known support mechanisms
for retaining the support arms 40, 41 in position may be utilized
thereby to prevent additional rotation of the support arms relative
to the mounted ballast housing 20. Additionally, the reflector
housing may be further positioned relative to the housing pin 62,
shown in FIG. 3, such that the housing is further aligned to the
proper head angle required by the end user.
[0043] As shown in FIGS. 11 and 11a, the fixture 10 of the present
invention may be equipped with a light leveler 65 as shown and
indicated. The leveler 65 may have angular measurement sides with a
level bubble 70 formed therein. As shown in the drawing, the sides
may have markings and are formed at differing angles such that the
reflector angle may be properly adjusted upon installation. Thus,
as indicated, the reflector 30 may be properly adjusted for either
short or long throw positions at 0.degree., 8.degree. or 12.degree.
from horizontal when the ballast housing is mounted to a wall or
other vertical surface. Alternatively, when a ceiling mount is
utilized, it may be desirable to adjust to 23.degree. or 27.degree.
from vertical for angular mounting. The bubble 70 in conjunction
with the sides of the leveler being at the desired angular
orientation allows for the proper adjustment of the reflector
housing 30. The use of the leveler 65 in combination with the
fixture of the present invention aides in the proper installation
of the fixture relative to the various surfaces and allows relative
ease of installation for both ceiling and wall mount.
[0044] The foregoing detailed description is given primarily for
clearness of understanding and no unnecessary limitations are to be
understood therefrom for modifications will become obvious to those
skilled in the art upon reading this disclosure and may be made
without departing from the spirit of the invention and scope of the
amended claims.
